When I had my RX100II, i found that it was too thick to comfortably fit in my jeans pockets (unlike my Canon S90, which is much thinner), so I ended up buying a small case for it or using my jacket pockets. I think this is the segment that Canon is aiming for with this product.

True Pocketable = Canon S120 3.9 x 2.3 x 1.1

Somewhat Pocketable = Sony RX100II 4 x 2.29 x 1.51

Somewhat Pocketable = Canon G1X Mark II 4.6 x 2.9 x 2.6

Being about half an inch larger in every direction completely removes it from being "jeans pocketable" but it'll still do fine in jacket or cargo pockets imo
